Abstract

The present invention provides a vertical air conditioner indoor unit, comprising: a housing; an air duct, the inner wall of which is adjacent to the air outlet is a tapered shape in which the flow cross-section gradually decreases along the air flow direction; and a flow guide A member, which is arranged in the air duct and defines an annular air outlet gap with its tapered part, is used to guide the airflow to the annular air outlet gap so that the airflow is gradually converged towards the center of the airflow under the guidance of the inner wall of the air duct and Flowing out of the air outlet and the air supply port in sequence; wherein the air guide is formed by rotating a guide line around a horizontal central axis, and the guide line includes first arc segments that are smoothly connected successively. , a concave second arc segment, a convex third arc segment, a convex fourth arc segment and a convex fifth arc segment. The vertical air conditioner indoor unit of the present invention has stronger wind force and longer air supply distance.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a vertical air conditioner indoor unit. Background technique [0002] Compared with the wall-mounted air conditioner indoor unit, the vertical air conditioner indoor unit has a larger number of horses and stronger cooling and heating capabilities, and is usually placed in a larger indoor space such as the living room. [0003] Since the indoor unit of the vertical air conditioner has a larger coverage area, it needs to have stronger long-distance air supply capacity and strong air output capacity. In order to realize long-distance air supply in existing products, the method of increasing the fan speed is usually used to increase the wind speed and air volume. However, the increase in fan speed will lead to a series of problems such as increased air conditioning power and increased noise, which will affect user experience. Contents of the invention [0004] The object...
